Salt Spray Test Requirements for ISO 4017 M10×120 8.8U TZN Screws & Standards

An important step in the quality assurance process is to conduct salt spray testing to verify the corrosion resistance of fasteners such as ISO 4017 M10×120 8.8U TZN screws . These tests assure the durability and reliability of the screws in typically corrosive environments, such as outdoor industrial areas. Here, we’ll cover the key requirements for the salt spray test for this specific screw, identify the applicable ISO standards, and provide detailed insights into its importance. What is the Purpose of a Salt Spray Test? A salt spray test is a standardized corrosion test used to evaluate the resistance of coated or uncoated materials to oxidation over time. This test examines how well the wall finish protects the substrate material from corrosion under adverse conditions for fasteners such as ISO 4017 M10×120 8.8U TZN screws. This test is essential for TZN (trivalent zinc-nickel) coated screws. Testing for the protective effect of these coatings is important because they are desig...
